Hi , When we are trying to access java external procedure from Oracle 11g in windows 7. it is giving the following exception.Devart.Data.Oracle.OracleException: ORA-29532: Java call terminated by uncaught Java exception: java.security.AccessControlException.
Please throw some ideas.

Please try executing the same external procedure with the same Oracle's user in different tool (e.g., SQL Plus). Maybe your Oracle's user doesn't have enough privileges. Also try running your program with the Run as Administrator option.
